In HM-15.0, TComSlice.h contains these two definitions:

UInt m_ltRefPicPocLsbSps[33];
Bool m_usedByCurrPicLtSPSFlag[33];

In HM-15.0+RExt-8.0, they are incorrectly defined as:

UInt m_ltRefPicPocLsbSps[MAX_NUM_SPS + 1];
Bool m_usedByCurrPicLtSPSFlag[MAX_NUM_SPS + 1];

From the spec it looks as though these arrays can be as large as num_long_term_ref_pics_sps, so the correct size for these arrays would be 32?

There are also a few incorrect asserts relating to these definitions.
